Quote from: buldawg76 on June 10, 2016, 02:33:31 AMTravisAre they listed for sale on your website yetI did a search for "SSG" on Wicked Air Rifles and nothing came up.
As promised!! fully internal SSG for the disco.... I used a prod hammer for the prototype but if I was to make these I would make the hammer myself because almost 20 bucks a pop the prod/challenger hammer is pricey not to mention the way hardened hammer plays *(&^ on drill bits trying to drill the threads out, The Mrod hammers are not hardened nearly as much as these are... ate one bit completely attempting it lol..... Also could make a lightweight hammer too but to be honest the disco hammer isn't that massive... anyways on to the pics!Hammer guide rod and nylock nut for preload adjustment... and the rear plug and aluminum machined gap adjustment, could also make from delrin if a black gap adjust was wanted... but machined this one from aluminum just because it looks good with my polished rear plug ..this is what it looks like installed.... the setscrew is what locks the gap adjustment after its been set.... also its long so that when you adjust the preload it also works as a stop for the nylock nut so you just need to use a flathead to adjust the preload....thats it pretty simple... uses stock disco size springs so you can put whatever spring you want in there for the tune your trying to get.... other then that it works like every other SSG... set your preload for your powerlevels/tune, set your gap, shoot........

The project came out beautifully, but I would not be able to re-create it... my machining kung fu is very very weak....like...doesn't exist.
I got the go ahead for a group buy thread...can be found herehttp://www.gatewaytoairguns.org/GTA/index.php?topic=110525.0only 5 slots for the first run!!

Adjusting the gap was hard because I was hitting the rear of the hammer sooner than I thought. I then switched measuring from the back of the gap adjuster (end of guide bolt to back of guide adjuster) using dial calipers with guide at rest to determine length. I then screwed in the gap adjuster and measured until I could see a change as I hit the rear of the hammer. Once I had that down, it was much easier to start dialing it in. The only thing I don't like is the amount of force required to pull the bolt back, it is not terrible, however there is a marked difference and makes me wonder about wear and tear on the bolt/handle. After shooting 80 pellets I was feeling it.This is only preliminary and I have more to do. I want to see if I can reduce the cocking force and once that is done I will drill my gap adjuster deeper so the guide will be mostly recessed to reduce any pinching possibilities. I'm using the my RVA as the SSG, which is probably why I was having conceptual issues.Before this, using just the RVA and preloading the spring and starting at 1800 PSI shooting down to 1050 PSI was averaging 801 FPS (at 3.5%) getting around 21 shots.I will post again with pictures once I’m done, it will be fairly similar to what you have already seen as I’m just copying. I hope my format makes sense. Dave
